hmm i would try to see if you could mesh the heat sink fins together to better help heat disipation from the esc to the colling unit above

I used a little piece of metal in the center of the ESC with thermal paste.

If you wanted to conserve some space you could also look into retro fitting a computer CPU water cooling unit. They are a little more compact and already have a cooling fan setup mounted to it.

I was thinking the same thing.

No, Costa Rica is an independent country.
Maybe you be confused with Puerto Rico.

+5 for creativeness - 5 for effectiveness, I don't quite understand the point of this, you are running 23/90 which is a bashing gearing, it should keep your temps below Fail safe 180*, second: heat sink on motor will reduce your temps by 15* which is about what you got, fan on ESC will reduce 5-10* temp on average, good fan for motor will reduce temps even more. The guys at my local hobby shop have done this many times to beat the heat, but for 31/76 gearing there is nothing that will help you to reduce it below 170*

First at all: Thanks for the review

Now, I am testing new gearings, I made a modification to the pump connecting the wires to the connector of the ESC. (Add more voltage and it can push more water), using tubes with more diameter and less curves, with the modification I made to the ESC the temperature goes down, i am adding fans to the esc and the radiator, and all the info I said before was before all the modifications made.

you will def get more cooling with the full alum gearboxes. I have the Hot racing graphite/alum setup, and while it does aid in cooling, it will not do as well as the flm or golden horizons you linked to.

As far as the coolent you are using.... In my full size turbo powered off road buggy I use a product called "Engine Ice" and it greatly reduced the coolent/engine temps. I don't know if that product is available where you are but it is also non corossive and biodegradable. Just a thought!!!!

Ok, thanks for the suggestion . I am going to search if these product exist here.

For a castle motor I wouldn't get the aquacraft water jacket. I would look at some aluminum ones made for castle motors. I've purchased a few for my boat and they don't leak at all. I would put a link but don't know if i can push others products.

^^^ I think its fine to post a link in this case as you need to reference a particular part to a particular person(reference purposes). Your not trying to turn the whole world on to the lowest price for it, but to show a member what else he could use for this application.

Update

I forgot say an update yesterday:
Yesterday i received a new gearbox, because my old gearbox have signs of fractures
Now with the picsSorry for the bad quality of the pics, it was taken with my cell phone.)

And i will fill that with ice. I will put the intake area of the pump through the bottom, and the warm water will come through the top , becoming cooled by the ice. i feel it will be more stable and less finnickey than the radiator method.

any thoughts???

I have the stock reciver on the vxl 16 merv, and i dont know much about the electrics of this project. What do i buy to attach the pump to the reciver, will it supply enough volts on my 2s lipos (7.4 v.), and would it just be easier to attach the pump to a 9v battery? would it work???
